AIIGUST VON LOEHR, OF VIENNA, AUSTRIA-HUNGrARYT WATCH-CASE.

SPECIFICATION forming partof Letters Patent No. 283,170, dated August 14, 1883.

Application filed March 20, 1882. (No model.) Patented in Germany November 17, 1880,No. 14,130,vin England November 19, 1880, No. 4,781, and in AustriaHungary January 4, 1881, No. 37,861, and No. 41,162.

To @ZZ wiz/0m, it may concern:

Be it known that I, AUGUsr von LOEHE, a subject of the Emperor of Austria and a resident of Vienna, in the Empire of Austria, have invented a certain Improvement in Watch-Cases, of which the following is a speciication.

This invention relates to watch-cases, and has for its Object such a construction of the same as will allow a watch to which this invention is applied to be kept always in one position, whereby greater correctness of its operations can be insured than is possible in a watch whose position is frequently changed.

Vatches as hitherto manufactured are ordinarily made of a circular rexterior shape, so that when carried in thepocket they can shift or turn, and no provision is made in the construction ofthe case for keeping the watch in the same position during the time when the watch is not being worn-as, for instance, during the night.

It is well known that Watches when placed in different positions vary considerably with respect tothe correctness of their indications, as the different positions cause friction and gravity to act differently upon the works,

. whereas, if the watch could always, or nearly always, be kept in the same position, the action of the saine would be materially improved.

The invention consists in the construction and arrangement of parts hereinafter described and claimed.

In the drawings, Figure l is a perspective view of a rectangular or square watch-oase adapted to receive a movement plate of a corresponding form. Figs. 2 and 3represent said movement-plate. Fig. 4 illustrates a watch with open cover standing in an upright position.

The caseA of the watch is made of a square or quadrangular forni, and is provided with the front and rear covers, B C, which are hinged to the case so as to open in the manner shown .in Fig. 1. The plate l), carrying or rectangular shape, and is inserted into the watch-case and secured therein in any approved manner. By using a square plate I gain space for the reception of the movement77 or train of gearing, and consequently I am enabled to employ a stronger spring-bal.- ance and gearing with a square plate than with a circular plate of the same width or diameter.

The square case proposed by me will permit the watch to be maintained in a perpendicular position in the pocket, thus avoiding the irregularities which arise when the position of a time-keeper is changed. Vhen the watch is removed from the pocket, it is held in a perpendicular position by opening one or both of its covers and placing it on a table or stand. l

As shown in Fig. 4, it will be seen that the iiat base of the watch-case and the open cover B constitute feet or supporting-surfaces for maintaining the watch in a perpendicular position, in order to insure its proper running at all times.

I am aware that watch-works have been fitted in articles of jewelery-sucli as chatec laines, crosses, Snc-and cases of angular forni;

but I am not aware that a pocket-watch possessing the advantages set forth by me hasever been suggested.

What I claim as new, and desire to secure by Letters Patent, is-

The pocket-watch herein described, having the square orl quadrangular case, the covers of a corresponding shape, height, and width, hinged to the sides of the case, and the movement-plate of the same shape as the case fitted into the latter, as and for the purpose set forth.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
